Cutting propagation method for coniferous trees

Abstract

The invention belongs to the technical field of vegetative propagation of plants and particularly relates to a cutting propagation method for needle-leaved trees. Preferentially, the needle-leaved trees are Torreya jackii Chun. The method particularly comprises steps as follows: (1) building of full-sunshine automatic spraying and cutting pool; (2) collecting and processing of cuttings; (3) cutting; (4) culture management after cutting; (5) management after transplanting. The method is simple and easy to implement, the propagation survival rate is high, the genetic change is small, management is convenient, large-scale propagation is facilitated, endangered plant, namely, Torreya jackii Chun can be effectively saved, and the survival environment of the species evolves to the north.

Description

technical field

[0001] The invention belongs to the technical field of plant asexual propagation, and in particular relates to a cutting propagation method of coniferous trees. Background technique

[0002] Torreya conifer ( Torreya jackii Chan ), also known as Torreya chinensis and Torreya japonica, belonging to the genus Torreya yewaceae, is a relict gymnosperm plant remaining from the Cenozoic Tertiary period, a precious tree species unique to my country, and a wild plant under national second-level key protection. The taxonomy and flora's climatic response to the Quaternary Ice Age are of great significance. In addition, the long-leaved torreya is hard and fragrant, and can be used to make utensils.

[0003] Long-leaved Torreya is an evergreen small tree or often a multi-branched shrub; branches are whorled or opposite, spreading or branchlets drooping; leaves are opposite, arranged in two rows, hard, linear-lanceolate, 3-13 cm long , 3-4 mm wide, first with acuminate ...
